Computer won't turn on after turning off while restarting

[jesussavesd]

I restarted my computer because the wifi wasn't working correctly. After about 20 minutes of the same restarting screen, I wondered if I might be better off shutting it down to stop the seemingly eternal restart. 

I may have been better off just being patient, but I was trying to get online to play with a friend who had been waiting for me and that didn't seem like a good option to make them wait longer. So I looked up what happens if you turn off the computer when it is restarting. Generally, people said it shouldn't be an issue if it wasn't updating, and that if it was an issue you would have to do system recovery. It hadn't given me an updating screen or shown any signs of an update so I thought it would be fine. I turned it off.

Now it won't turn back on. When plugged in the red power light shows, but other than that nothing. I've tried to turn it on using the power button multiple times. I think I probably ruined the computer. If anyone can help, please do. Thanks.

IF the drive is failing, then drivers files could be corrupted and that would prevent WiFi from working.

And, if the restart just hangs with no progress, that is a clear indication of a failing drive.

So, let's check that first, because if it is failing, it would need to be replaced and there is no point then in doing anything else until we confirm that.

If your PC is new enough to support UEFI, you can use these steps to test the HDD (Hard Disk Drive): http://support.hp.com/us-en/document/c00439024

If not, to check the HDD you have to follow these steps:
1) Press Esc key repeatedly, several times a second, while rebooting the laptop. Do NOT hold the key down, just press it over and over.
2) Eventually, you will see an HP Startup Menu
3) Press the Function key for testing the hard drive (usually F2) and let it run.

If the drive checks out OK, then report that and I can provide you options for reinstalling Windows on your PC.

Please note that if your model has an SSD instead of an HDD, these diagnostics might not work properly.
